IMPROVEMENT lN ELECTRO-MAGNETIC ENGINES.

Specification forming part of Letters Patent No. l22,944, dated January 23, 1872.

Specification describing certain Improve l tral bar, and the ends of which project to equal ments in Electro Magnetic Engine, invented by CLAUDE V. GAUME, of Y'Villiamsburg, in the county of Kings and State of New York.

Figure l is an end view of my improved engine. Fig. 2 is a side view of the same, partly in section through the contact wheel.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved electromagnetic engine, simple in construction and effective and reliable in operation, being so constructed as to be free from the pull back or retardation which is a great objection to such engines as usually constructed; and it consists in the construction and combination of various parts of the engine, as hereinafter more fully described.

A and B are the side frames of the ma chine, the lower parts of which are connected and held in their proper relative positions by the cross-bars (J, to each of which is attached a horseshoe magnet, D, the arms of which are provided with a coil, E, in the ordinary manner. Each of the coils E is connected by a wire, t, with the cup or clamp F, which receives the wire leading to the negative pole of the battery, and which is insulated from the frame A by a rubber tube or other suitable non-conducting means. The wire leading to the positive pole of the battery is connected with the frame A by the cup or clamp G, the said frame A thus forming part of the circuit. H is a wheel attached to the shaft 1, which revolves in bearings in the upper part of the frames A B, and which thus forms part of the circuit. The wheel H is made of such a size that the armatures J, attached to the face of the said wheel, may come so close to the poles of the magnets D as to be attracted by said magnets when the circuit is closed.

The armatures J are formed as shown in Figs. 1, 2that is to saythey consist of a central bar attached at its center to the face of the wheel H, and having cross heads formed upon them about midway between its centers and ends, said crossheads having short bars formed upon their ends parallel with the cendistances upon the outer and inner sides of said crossheads.

Armatures thus constructed are found to be free from the retardation or pull back which was the great difficulty to be overcome in making electromagnetic engines practical as a motive power.

To the end of the shaft I is attached a wheel, K, of wood or other suitable non-conducting material. The face of the wheel K is covered with plates L L of copper, alternate- 1y short and long, which plates are separated and insulated by ivory or other suitable nonconducting keys M. The short plates L are attached to the ends of the arms or rods N, which pass in radially through the wheel K, and the inner ends of which are in contact with the shaft 1, as shown in Fig. 1. O are small wheels which roll along the face of the wheel K, and revolve upon the journals of the arms P, which are attached to the upper parts of the frame A. The arms P are insulated from the frame A, and have wires Q connect ed with them, and leading to the coils E, completing the circuit.

Vith this construction, when the machine is connected with the battery the current of electricity passes through the frame A, shaft I, and arms N to the plates L. As the wheels 0 come upon the small plates L the circuit is closed, and the current passes on through the wheels 0, a ms 1, and wires Q to the coils E, and through the wires It back to the battery. When the circuit is closed the magnets D at tract the armatures J, and when the circuit is broken the said magnets cease to attract said armatures.

The plates L of the wheel K and the armatures J of the wheel H are so arranged that the wheels 0 will come upon the plates L to close the circuit successively as an armature approaches the successive magnets D, and will come upon the plates L successively to break the circuit as the armature is upon the point of leaving the said magnets, the construction of the armatures J, preventing any drawback or retardation as the armatures are leaving the magnets.

Havingthus described myinvention,Iclaim allel to central bar, and whose ends project as new and desire to secure by Letters Pat equally upon the outer and inner sides of said ent' cross-heads, as described.

The armature J formed of a central bar, at- CLAUDE VICTOR GAUME. tached to Wheel H at its center, and having Witnesses: cross-heads between center and ends that are JAMES T. GRAHAM,
